导航

An algorithm of Dead Reckoning/Baro-altimeter integrated navigation is presented, and proved experimentally.

给出了一种实用航位推算／高程计组合导航的算法，并进行了实际跑车验证。

Dead reckoning is the use of maps and known landmarks combined with aircraft airspeed to determine position.

但至于你说的导航，这个对于以VFR为基本原则的直升机，根本就不是个问题。

The idea was that instead of trying to predict the future (the principle of Dead Reckoning), why not make the past look like the present?

其中有一个想法是，除了试图预测未来之外(也就是导航预测算法的原理)，为什么不可以将过去的情况作为现在来处理呢？

The dead reckoning system constructed by strapdown inertial navigation system and velocity-measuring device is studied.

本文对由捷联惯导和测速设备所搭建的航位推算系统进行了研究，提出了一种基于航位推算系统的组合导航算法。

After building Singer athletics model, the new algorithm has been applied in "Test-1" Robert' s dead reckoning athletics. The system' s precision has been improved .

然后建立了水下机器人运动的辛格模型，对推算得到的位置量进行了最优估计，较好的提高了导航的精度，增强了系统的鲁棒性。

With indefinite noises and nonlinear characteristics, real-time estimating states of the dead reckoning unit is much more difficult than that of the other measuring sensors, which used in vehicle integrated navigation systems.

由于噪声的不确定性和自身的非线性特征，通过航位推算系统精确地估计车辆的状态是实际车辆组合导航中最困难的部分。

Gps as a starting point in order to achieve the case, dead reckoning navigation to achieve calculation speed and angular velocity of the object to draw the object distance and course.

详细说明：实现在以gps为起点的情况下，组合导航实现航位推算，计算物体的速度和角速度，从而得出物体的距离和航向。

The position precision of Dead Reckoning and Strap-down Inertial Navigation System is higher in little time,but the error will be more and more emanative along with time.

由于水成为一个有效的法拉第笼，所以许多基于电磁传播的导航方法在水下不易实现。

Such writings suggest that those satellites, and navigation and early-warning satellites,"could be among initial targets of attack to blind and deafen the enemy," it said.

如此的描述暗示，一些卫星和导航，预警卫星"能够成为最初的攻击目标，这种攻击足以使敌对方盲、聋"。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
